Wyrm

Scenecore Helminthologist who gets infected by a parasitic worm from their workplace and has to hurry to figure out a way to remove the parasite or kill it before it can take over their brain. However, as long as the worm is attached to them, it cannot spread or reach others so the worm tries to desperately take over (and in the few times its successful, ends up being well-liked by some of the people in the scientist's life) The two argue constantly, the worm saying they deserve a body and would be wanted more by the people around them, and wants to steal the rather nice life the scientist has built up for themselves while the scientist is constantly fighting back to keep what they worked so hard to built.
